Re: AOC Monitor Question (Hz)
The screen tearing in game is due to higher fps than the refresh rate. The black bars or whatever when running at 75hz is because as pointed out the monitor doesn't support 75hz at that resolution. When that is the case, sometimes the monitor will display something but it won't look right and I'm pretty sure you could damage the monitor. If you want to run the game at 1920 you'll have to run the monitor at 60hz. As far as the mouse lag, is that when you turn v-sync on from within the game? If so, try turning it off in game but forcing it from the nvidia control panel, maybe that won't cause the lag. Not sure but it's worth a try...
